> We'll need metrics in order to gain visibility into the maintenance
> functionality. This will also allow operators to add alerting on these
> metrics, in particular:
> # Number of scheduled hosts.
> # Number of active windows.
> # Number of expired windows.
> # Number of successful drains.
> # Number of failed drains.
> As an example of an alert guideline, we would want to know the number of
> expired windows as a gauge to ensure that it is not growing excessively. This
> allows alerting to catch when operators are not properly unscheduling
> maintenance once it is complete.
